Patented July 4., 1916.

, `A `Applicetionfiled January 28, 1913. Serial No. 744,658. I

To all whom it may concern:

Be it known .that we, ALEXANDER E., KEITH, of Hinsdale,` Dupag'e county, lllinois, and Mier-nini. Srrrrnn, of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Sho-"k or Vibration Absorbing Apparatus for Vibrating Bodies or Vehicles, of which the following is a specification.' Y

This invention relates to that type of apparatus designed to be interposed between two relatively movable bodies, a movement' in one of which causes a corresponding inovcf ment in the other, as for example, between the body and axle of a vehicle, such as 'an antomobile, for the purposeof 'reducing or re-A tarding, or both reducing and retarding the movement of the responding member. Such a device, when applied to a-vehiclc, will enable it to run `over a comparatively rough road and yet prevent the rider. from being disagreeably jolted.

Among the objects of our invention are to provide a form of shock absorber that is both strong and comparatively cheap to manufacture; to provide a form, the fluids. in which will not leak and the parts of which will not be liable to work loose and. which may be conveniently and effectively fastened in working position; to provide a'- form, the fluid chamber of which may be bored bya simple and inexpensive operation; to provide a forni which may he interchangeably used on either side of a vehicle; to provide a more satisfactory and ellieient shock absorber' than heretofore and to provide details of in'iprovemcnt tending to increase the efficiency and scrvieeability of a shock absorber ot the above character.

Our invention, to accomplish the foregoing,r and other useful ends, consists in matters hereinafter set forth and claimed.

In the aecou'ipanying drawings, Figures l and 2 are an elevation andplan, respi-.cv ti vely, ot the device, and show one manner in which it may be applied to a' vehicle, for example. Fig. L is a transverse section taken on the line of Fig. 2. Fig. 4 is a vertical section taken on the line flw-'let Fig. ["igg. 7 illustrates how the device may be applied to both sides of a. vehicle.

ln the drawings, A reprfsents a portion ot the body and il the axle ot a vehicle to which the shock absorber has been attached. S shown, this device comprises a, cupdike cylinder C, which is suitably secured` to the body A. lVithin this cup is-contained a rcanism designed to, cooperate with thesainc..

This cup is provided with a covcrl), inte-i once in position 'the metal around 'the lip lt.

of the cup is folded over as shown pinching @he coverin position and insuring a.' tight joint which will insure.' against 'leakage f5 tardingr fluid, such as oil, and suitable mechter the device goes intense. The said cover D is provided with a. bearing, 'through which a spindleGlpassest- 'This spindlcvis termed a rotary piston, which comprises the wings Il and l'. This spindle and piston are Apivoted` on' tlic boss M, which is located in the center ot' the bottoni of thc cup. These piston wings are provided with suitable cl1cc valves t and 1'., which lpermit the fliid cont. med -within the cup to pass therethronghiwghen the piston isrotating in one directioil,flint not while rotatingr lin-thevopposite direction. '.lhe hearing is provided with a. collar J, through which the spindle passes and which is contained within the bearing-*box K. provided, as shown, the usual packing material, which packing material is followed 'by the usual wedge collar, which latter isin.

turn vcontrolled `by the -cap L which, as shown, is screwed tothe walls of the bearing box K. This cap L, as shown in Fig. 1, is

provided withlngsM, which are engaged by a spring catch N to prevent it from working loose. The end of the spindle G beyond the iackinff box is desifned to receive a crankl arm O. This arm, as shown, is pivotally linked to the rod Vl, which is rigidly secured.

maA

Next to this ring there' is with respect to the `axle B, causes the spindle (i .and the wings Il and 4,I to rotate in a countereloeliwise direction, as viewed in Fig. 2i. 'l`he valves in the. wings, Il and I permit the tluid to pas through them freelyduring the. movement in this direction 7 and little or no resistance ihollered tothe downthe wings ll and' I begin to rotate. in 'the oppositedirection, when the bodyV ot" the vehiele beginbv .to move upward,;

elozse. and the llluid cannot now pa them, but is forced to eseape'through -the spaces .left near the walls of the eup. .'I`hese spaces are, of eourse, adjufted tol permit., the

esi-ape to taliev plaee at any suitable. ratei.

Of course, it is perfectly obvious that the valves /t and may be placed o n the. opposite 'sides of their respective 'ningsirix'i which over thel spindle G, 'is slipped into place to rover this openingr and a,tth' e""siii'ie time hold the spindle -tji in positionf This \\a.\zher. together with the packing'that vis inunediately next to it produces 'a bearing tight enoughtopi-eventleakage of theeil or other lluid.

. It will be. seen therefore. that wevpro'vide le A:al\'.us,-'.,i1.i;tlie .art and consequently a dev-ice which through ean"lie made cheaper than otherb` of the kind.`
